[0001] The present invention relates to a physiotherapy apparatus of the type used for the treatment of articular rigidity by means of passive mobilizations, through the application of controlled mechanical traction forces.
BACKGROUND OF THE INVENTION
[0002] Some known physiotherapy apparatuses present a table, similar to a stretcher, which has a displaceable part, for example for applying traction axially to the cervical and lumbar column of a patient.
[0004] The known apparatuses nevertheless have the disadvantage of being rather unversatile, for they can be used only for some specific applications. This makes it difficult to amortize their cost, especially in the case of relatively small treatment facilities, which have to have a whole range of apparatuses of this type. Moreover, not all the mobilization movements are covered by the known apparatuses, and many of said movements have to be carried out manually. Another disadvantage associated with known apparatuses is the absence of reliable systems for controlling the force and the traction cycles which are applied to the patient, while also permitting adaptation to each specific case.
[0005] The above-mentioned apparatuses also have the disadvantage that it is not always possible to secure the parts of the patient's body in an optimum manner, and it can therefore occur that, for example, the traction is not limited to the joint to be treated.
DESCRIPTION OF THE INVENTION
[0006] The objective of the present invention is to resolve the aforesaid disadvantages, by means of a physiotherapy apparatus which is highly versatile and permits treatment of the cervical and lumbar vertebrae, hip, shoulder, elbow, knee and ankle, simply by displacing the position of some members of the apparatus, and which at the same time permits reliable, adjusted control of the traction cycles and can adapt them to the specific needs of each patient.
[0007] In accordance with these objectives, the physiotherapy apparatus of the invention for the treatment of articular rigidity comprises a table on which the patient is placed, made up of a static board and a moving board, with said moving board being displaceable towards and away from the static board, and means for applying a traction force between parts of the patient's body; and it is characterized in that the said moving board is mounted in such a way that it can also rotate about a horizontal axis, between a horizontal position and an inclined position, and about a vertical axis, between two end positions which are symmetrical with respect to the longitudinal axis of the table, and in that the said means for applying a traction force between parts of the patient's body include at least one traction cord and a system of pulleys with which said cord is associated in order to apply the traction to a joint of the patient in a desired direction.
[0008] According to one characteristic of the invention, the moving board comprises: a lower base attached to a horizontal bar, which can rotate with respect to some supporting uprights of the table, such that the board rotates between said horizontal and inclined positions; an upper plate, which can rotate with respect to said lower base about an axis perpendicular thereto, in order to effect rotation between said two symmetrical end positions; and a pair of guides, fixed to said upper plate, upon which the moving board can be displaced towards and away from the board.
[0009] Preferably, the apparatus is provided with elastic means which tend to keep the moving part in a symmetrical position with respect to the longitudinal axis of the table and close to the fixed board.
[0010] In accordance with another aspect of the invention, the static board is made up of a first end member articulated around a first horizontal axis, a fixed second end member, a first intermediate member articulated around a second horizontal axis parallel to the first axis and a second intermediate member articulated around a third horizontal axis parallel to the first and second axes.
[0012] In one embodiment, the moving board can rotate around the vertical axis through an angle of up to about 30° in each direction from an initial position of symmetry, and can rotate around the horizontal axis through an angle of up to about 50°.
[0013] In one embodiment, the apparatus also includes a plurality of anchorage points for releasable attachment of straps for securing the various parts of the patient to the static board and to the moving board.
[0014] Preferably, these anchorage points are formed by horizontal rods fixed to the upper surfaces of the boards, the boards being fitted with covers of flexible material which have openings in correspondance with said rods, and whose thickness is sufficient so that the anchoring rods do not project from them.
[0015] In a preferred embodiment of the invention, the apparatus comprises a base, on which are mounted the supporting uprights of the table and a supporting structure for an adjustable traction motor to which are attached two traction cords, the aforesaid system of pulleys comprising at least one driving pulley situated on the support structure beside the motor, one double return-pulley situated at the end of the base adjacent to the motor-support structure, a pair of horizontal pulleys situated at the opposite end of the base with respect to said return-pulley, each one of which guides one of the two traction cords through an arc of 180°, and a pair of pulleys displaceable along corresponding longitudinal guides fixed to the base of the apparatus, each one of said displaceable pulleys guiding one of the two cords to orient it in a desired direction.
[0016] According to a variant of this embodiment, the pulley system also includes a pair of pulleys which can move vertically along two guides fixed to the motor support structure, and a pair of pulleys which can move horizontally along a guide mounted on the motor support structure, this latter guide being able to move vertically.
[0017] In another variant, the pulley system also includes at least one pulley mounted on a support for cervical vertebrae traction, which can be fixed releasably on the motor support structure.
[0018] Advantageously, the physiotherapy apparatus further includes a set of two parallel guides which is mounted laterally with respect to the table and at an adjustable distance therefrom, at least one lateral pulley mounted on a slider being able to slide along said guides.
[0019] Also advantageously, the apparatus includes another guide on which a central pulley can move, said guide being mounted attached to the lower base of the moving board, substantially perpendicular thereto and centered on the longitudinal axis of the table.
[0020] Preferably, at least one of the aforesaid pulleys has associated to it a cord-direction guiding pulley mounted perpendicularly to it and having a rotation axis mounted in such a way that it can turn around it.
[0021] According to a preferential characteristic of the invention the apparatus also includes supports for the legs, mounted adjustably and releasably on the moving board, and attachments for the feet, with adjustable inclination and position, mounted releasably on the base of the apparatus.
[0022] Preferably onto one of the end members of the static board are fixed laterally a pair of vertical, telescopic bars, bearing at their upper ends rods for the attachment of straps for securing the shoulderblades of a patient.
[0023] The apparatus includes straps for securing the patient or for coupling with the traction cords, which straps, in one embodiment, have a band destined to extend around one part of the patient's body, to which are linked two tubular fitments provided with means of adjustment for the two cords which are inserted into same.
[0024] In an alternative embodiment, the straps have a band destined to extend around one part of the patient's body, to which band is attached a strip whose free end forms an eye for coupling with the aforesaid anchoring rods provided on the surfaces of the boards.
[0025] Advantageously, a control module is associated with the adjustable traction motor, the module having a plurality of pushbuttons for setting the treatment parameters, a starting pushbutton, displays for the selected parameters, indicator lights for the selected treatment and treatment phases, a set of alarms, an emergency stop button and a connector for a remote-control cable.
[0026] The motor control module can be used to program, display and monitor various parameters of the treatments, such as traction force, relaxation force, traction time, time of the traction/relaxation cycle, total treatment time, traction and relaxation speeds and others.
[0027] Preferably, the control module includes a non-volatile memory for storing the standard values for each treatment.
[0028] A standard program can thus be executed for each case, or one, several or all of the treatment parameters can be changed, thereby effecting a readjustment which makes all the values of force, time of each phase, traction speed, etc., suitable for the severity of the pathology and physical constitution of the patient, without deprogramming the session started.
[0029] Advantageously, the motor support structure is fitted with a pair of horizontal telescopic bars provided on one of their ends with at least two pulleys. These horizontal bars permit the cervical-vertebra traction forces to be oriented to any desired degree.
[0030] Preferably, the physiotherapy apparatus of the invention can also include a guide, which is mounted laterally with respect to the table and at an adjustable distance from same, on which guide can slide a vertical telescopic bar provided with at least two pulleys on at least one of its ends.
[0031] Advantageously, the physiotherapy apparatus of the invention can be taken apart into at least three parts to facilitate transportation thereof.
BRIEF DESCRIPTION OF THE DRAWINGS
[0032] For a better understanding of all that has been set out some drawings are attached which show, schematically and solely by way of non-restrictive example, a practical case of embodiment of the apparatus.
In said drawings, Figure 1 is a perspective view of the physiotherapy apparatus of the invention;
Figure 2 is a side elevation view of the part corresponding to the table;
Figure 3 is a perspective view of an accessory of the table; and
Figure 4 is a perspective view of an accessory of the alternative table to the one shown in Figure 3.
DESCRIPTION OF A PREFERRED EMBODIMENT
[0033] One embodiment of the physiotherapy apparatus of the invention is shown schematically in perspective view in Figure 1.
[0034] As can be seen, it essentially has a base 1, on which are mounted a table 2 and a support structure 3 for a traction motor 10.
[0035] The table 2 is mounted on the base 1 by means of four telescopic columns 4, so as to make it height-adjustable.
[0036] The table 2, which can be seen in greater detail in the elevation view of Figure 2, is made up of a static board 5 and a moving board 6; the static table 5 is in turn made up of a first end member 7 pivoting around a first horizontal axis, a second fixed end member 43, a first intermediate member 8 pivoting around a second horizontal axis parallel to the first and a second intermediate member 9 pivoting around a third horizontal axis parallel to the first and second axes.
[0037] The moving board 6 can move on guides 12 fixed to an upper plate 13 which is in turn mounted in rotary fashion with respect to a lower base 14; this last is fitted pivotally by means of a bar 15 onto the table, so that the moving board 6 can be inclined by rotating around this bar.
[0038] The moving board 6 can therefore carry out three movements: inclined with respect to the table (up to approximately 50°), rotation around an axis perpendicular to the plane of the board itself (up to approximately 30° either side from a central position of symmetry) and withdrawing and approaching movements with respect to the static board of the table.
[0039] Some springs 16 keep the moving board 6 in its position closest to the static board 5, and to move the moving board 6 further away the force of these springs has to be overcome.
[0040] Clearly, the three movements of the moving board could be implemented with a mechanical arrangement different from that described or shown; moreover, each one of the movements can be carried out manually or driven by an electropneumatic actuating device or the like.
[0041] The moving board and all the members of the fixed board are provided with covers of flexible material 17 in order to improve patient comfort; these covers have a number of openings, inside which are the anchorage points for the straps used to secure parts of the patient's body to the table.
[0042] The anchorage points are provided both on the static board 5 and the moving board 6. Specifically, on the static board, the first intermediate member 8 includes four anchorage points 8a arranged in pairs near both sides of same, these anchorage points 8a being slightly inclined and serving for securing the arm in elbow movement manoeuvres. The first intermediate member 8 also includes a pair of anchorage points 8b fitted close to the first end member 7, which are used for securing the shoulderblade. The second intermediate member 9 includes a pair of anchorage points 9a fitted beside the second end member 43, which are used to secure the pelvis during hip traction. At the central part and at the same height from said anchorage points 9a is fitted a third T-shaped anchorage point 9b used to secure the thorax during lumbar traction. The second end member 43 includes a single anchorage point 43a situated beside the moving board 6 and centred, which is used to secure the thorax in lateralized lumbar traction. The moving board 6 includes two orifices 6a made close to the fixed board 5 in order to secure the pelvis. It also has four anchorage points fitted on the opposite end of said moving board 6 in order to secure the thighs in knee-movement manoeuvres. The moving board 6 also has a pair of anchorage points 6c to secure the pelvis when the patient is seated.
[0043] The support structure 3 of the motor 10 (Figure 1) is formed of a number of uprights 20 and vertical tubular guides 21, and also has a horizontal tubular guide 22, adjustable in height, which supports a bar with two pulleys on either end and a central attachment control for lateralization in the corresponding traction movements.
[0044] The base 1 of the apparatus is provided with three longitudinal tubular guides 23 and two return-pulleys 24.
[0045] The apparatus also includes a plurality of pulleys, which will be described in detail below but have not been shown in Figure 1.
[0046] The apparatus of the invention is completed with a number of accessories, shown in Figure 1 in their position of use: supports 26 for the legs, made up of a unit which can be attached to the moving board 6; tiltable attachments 27 for the feet, made up of a unit which can be attached to the base 1 of the apparatus; adjustable vertical bars 28, for example telescopic bars, fixed to the first end member 7 of the static table 5, which serve to secure the shoulder of a patient by means of straps, for which purpose they have a rod 29 on their upper end; and finally a side unit 30 of two parallel guides, which is attached to one or the other side of the table when lateral traction is required, and inside which can be fitted a pulley mounted on a slider.
[0047] Both the support 26 for the legs and the attachments 27 for the feet are fitted onto the apparatus only when required.
[0048] The side unit 30 is shown schematically in perspective view in Figure 3, and includes two horizontal guides 31 and 32, parallel to each other and linked by vertical bars 33, which can be associated with either side of the table by means of a coupling bar 34, which is inserted into a corresponding cavity so that the guides 31,32 are at the desired distance from the table.
[0049] Inside one of the guides 31,32 can be fitted a slider 35 which is fixed in position by means of a fixing knob 36 and on which are mounted two pulleys 37,38; the pulley 37 is fixed to the slider and can rotate freely about its axis, while the pulley 38 is mounted in freely rotary fashion around the pulley 37 and around its own axis. The function of this second pulley 38 is that of guiding the cord in such a way that it always remains in the correct direction of traction.
[0050] Alternatively, the unit 30, on the table 2 side, can be fitted with the member shown in Figure 4, which comprises a guide 46, mounted laterally with respect to the table 2 and at an adjustable distance from it, on which guide 46 can slide a vertical telescopic bar 47 provided with a triple pulley 48 on one of its ends. This vertical bar 47 permits traction movements on the upper limbs to be carried out.
[0051] In order to use the apparatus described, at least one traction cord (not shown in the figures) is made to pass from the traction motor 10 through a number of pulleys, which vary depending on the joint to be treated, and is secured to a strap which is adjusted around part of the body of the patient in order to exercise a traction force on same. At the same time, the fixed part of the patient is in each case suitably immobilized, for example by means of another strap which fixes the corresponding part of the patient's body to the table, using the anchorage points provided for the purpose. The patient will be placed in a particular position in function of the treatment to be carried out. Descriptions are provided below by way of example of some specific treatments.
[0052] The apparatus described therefore incorporates a number of pulleys, some of them fixed and others in adjustable position, so that the traction cord or cords can be guided towards different positions of the apparatus. Some of these pulleys are mentioned below, with reference to Figure 1.
[0053] The motor support structure 3 is provided with a driving pulley 40, through which passes a cord, the end of which is attached to the traction motor 10 outlet. On the base 1 there are two return pulleys 41, which divert the cords which then run along one of the longitudinal guides 23 (the central guide); at the opposite end of the table, each cord passes through one of the return pulleys 24 and returns along one of the longitudinal guides 23.
[0054] On these guides are provided pulleys 42 of adjustable position throughout the length of the guide, from which pulleys the cords can be directed towards different points of the apparatus.
[0055] The vertical tubular guides 21 and the horizontal tubular guide 22 are also provided with adjustable-position pulleys (not shown).
[0056] The system of pulleys also includes an adjustable-position pulley inside a guide fixed to the lower board of the moving board 6 (not shown in the drawings), being therefore situated under the table, and also a pulley mounted on a bracket for cervical vertebra traction (not shown), which can where necessary be attached to the motor support structure 2.
[0057] On the motor support structure 2 are provided a pair of horizontal telescopic bars 44 one of whose ends has a triple pulley 35. These horizontal bars 44 allow cervical vertebra traction forces to be oriented towards any degree.
[0058] In order to immobilize part of the body of the patient during a treatment session, and also to apply traction to the joint to be treated, a number of straps have been provided: depending on the use of each strap (to secure the patient's body to the table or to secure a limb in order to apply traction to it) and on the part of the body for which the strap is used, several types of straps can be provided, only some of which will be described.
[0059] Some straps have a band destined to run around a part of the patient's body, to which band are attached two tubular fitments provided with means for tightening onto two cords inserted into them; others have a band destined to run around a part of the patient's body and have attached to them a strip whose free end forms an eye for coupling with some anchoring rods provided at suitable positions on the surfaces of the boards.
[0060] The tightening of some of the straps can be carried out with Velcro-type closures; the straps which are destined for attachment to the part of the body subjected to traction (instead of to the fixed part, secured to the table) have means for tying one of the traction cords to same.
[0061] Specified below are some of the various treatments which can be carried out with the physiotherapy apparatus described, which include traction movements on the large joints over any arc within the articular limits according to the therapeutic needs of the patient.
a) Cervical column: axial traction, or traction with right or left lateralization component. Patient position: dorsal decubitus with or without cervical flexion.
b) Lumbar column: axial traction, traction with right or left lateralization component, anti-lordosis manoeuvre. Patient position: dorsal decubitus with suitable degree of lumber delordosis.
c) Shoulder: axial traction in any articular arc of suitable abduction, caudal-transfer traction in any suitable articular arc of abduction, side transfer traction in any suitable articular arc of flexion according to pathology. Patient position: dorsal decubitus.
d) Elbow: dorsal transfer movements in any suitable arc. Patient position: dorsal decubitus.
e) Hip: axial traction in any articular abduction arc, caudal- or lateral-transfer traction in any articular flexion arc, axial abduction within the articular limits. Patient position: dorsal decubitus.
f) Knee: axial traction in any articular arc, with varus or valgus component, dorsal-transfer traction in any articular flexion arc, ventral-transfer traction in any articular extension arc, angular mobilizations in any articular flexion and extension arc. All the movements can also be carried out with a rotation component. Patient position: seated or decubitus, according to the manoeuvre.
g) Ankle: axial traction, dorsal-transfer traction, ventral-transfer traction, all in any articular arc. Patient position: seated.
h) Wrist: axial traction in any flexion or extension position, and with any cubital and/or radial deviation component desired.
[0062] A detailed description of some of these treatments is provided below; as will be seen, in each case the patient must be positioned and immobilized suitably, and this will vary considerably from one treatment to another, so that the versatility of the apparatus described is of considerable importance.
[0063] For treatment of the shoulder, for example, the patient will lie flat in decubitus, with the head resting in the first end member 7 of the static board 5 of the table (see Figure 1), and part of the shoulder is immobilized using a strap which is secured to the adjustable vertical bar 28 situated on the opposite side of the table from the shoulder to be treated. A traction cord is then made to pass from the pulley 42, situated at an intermediate point on its corresponding longitudinal guide 23, through the pulleys 37,38 mounted at a suitable position on the unit of parallel guides (Figure 3), and is attached to a strap which secures the patient's arm. A suitable traction cycle is then carried out. It should be noted that the rotary pulley 38 ensures optimum direction of traction at all times.
[0064] In the case of lumbar treatments, the patient is also positioned with head resting on the first end member 7 of the static board 5, and is immobilized as follows: the chest is secured by means of strap to the static board 5, and the abdomen is secured by means of another strap to the moving board 6; the moving board 6 is then oriented in the desired way, thanks to its two possible rotations, a traction cord is attached to this moving board and the desired traction cycle is then carried out.
[0065] In the case of ankle axial and transfer treatments, the patient sits on the moving board 6, while the end member 9 of the static board 5 is raised and used in this case as backrest.
[0066] The patient's foot is immobilized in the attachments 27 by means of a suitable strap, and the desired traction cycle is carried out through another strap attached to the leg above the ankle. Depending on whether the traction is dorsal or ventral, the pulley 42 which guides the traction cord will be situated at a particular position along the longitudinal guide 23.
[0067] The traction motor 10 is adjustable, in order to provide the traction force best suited to each case; in order to permit reliable and safe operation the apparatus is provided with a motor 10 control module (not shown) which includes a plurality of pushbuttons for adjusting/setting treatment parameters, a start button, displays for parameters selected, and indicator lights showing the treatment selected and the treatment phases.
[0068] The control module permits programming of: treatment type (cervical, lumbar vertebrae, etc.); treatment time, following which the motor stops and the cord loses tension; traction and relaxation times and forces; and traction and relaxation speeds.
[0069] Once the parameters have been programmed, the start button causes the treatment to start and the apparatus will switch automatically between traction and relaxation in accordance with the programming carried out.
[0070] For greater safety, the control moduls further includes a set of alarms, an emergency stop pushbutton and a connector for a remote-control cable, so that both physiotherapist and patient can stop the treatment if they deem such to be appropriate. There are also detectors which halt operation of the apparatus is there is any overload, for example, if the force exceeds the programmed value by 10% or if stretching breakdown occurs.
[0071] The control module includes a non-volatile memory for storing the standard values for each treatment; once the treatment has started, one or more parameters can be altered from the control module in order better to adapt the treatment initially set to the needs of each patient.
